2206 2RS Double Row Self Aligning Ball Bearing

2206 2RS Double Row Self Aligning Ball Bearing is a cylindrical bore bearing usually made of chrome steel with two rubber seals on both sides, a nylon or steel cage, a spherical outer ring raceway, which can compensate angular misalignment and resist contaminants while bearing large radial loads and certain axial loads.

Technical parameter:

The main features of self-aligning ball bearings are:

(1) The outer ring raceway of the self-aligning ball bearing is part of a spherical surface, and the center of curvature is on the bearing axis, so the bearing has the aligning function, and can be automatically adjusted when the shaft and housing are flexing. No additional bearing burden.

(2) It can withstand radial load and appropriate axial load in both directions. But can not withstand the torque load. The contact Angle of this kind of bearing is small, the contact Angle under axial load is almost unchanged, the axial carrying capacity is small, the radial load capacity is large, and it is suitable for heavy load and impact load.

(3) Double-row aligning ball bearings with tightening sleeves and locking nuts can be installed at any position on the optical shaft without the need to locate the shaft shoulder.
